Donbalon is a second-level Nightmaren and a villain in NiGHTS: Journey of Dreams.
Donbalon is a four-tailed blue jester hat with red bells, with a pink jewel on his forehead, purple glowing eyes, under which is scar-themed makeup. He also has a red nose and purple skin with thick, grinning lips. There are feathers, and a jacobean ruff around his neck, with his ensamble ending in a waistcoat. His arms are very long and thin wires, ending with white gloves and long, thin, spiky fingers. He has a very spherical body almost like a balloon (similar to Puffy) with patchwork.
Donbalon is the boss of William Taylor's Pure Valley dream. The strategy is very simple. Donbalon appears from curtains at the bottom of his arena, at this point, NiGHTS will have to launch him through his circus-themed, nightmarish arena (avoiding hitting obstacles for Donbalon to bounce off of) toward the top, where he is destroyed upon impact with the spiked ceiling.
- Donbalon closely resembles Puffy from NiGHTS into Dreams, not only because of his sphere-like shape, but also in technique.
- The name of Donbalon's theme is "Drifting Donbalon".
- In Spanish, "Don Balon" means "Sir Ball".
